NH-D15 Configuration.

[Pw.a]

Recently, my AIO died. While waiting for RMA, I bought an nh-d15 to use. Due to the problem of chassis and ram, I can't install the fan in front of the tower. So I installed them as shown in the picture, behind each tower and tried to pull air. In terms of performance, there is no problem. My 5900x is max at 67 degrees Celsius in cinebench R23. I want to know if this configuration is correct, and will it be better if I need to put a 120 or 140 fan in front of the tower.

 

Tanks a lot for help!

That's fine, no need to buy another fan, especially if it's just a solution until you get a replacement AIO (though an NH-D15 as a temp cooler is pretty overkill).
